Intel Multiprocessor Specification v1.4. The Intel SDM claims that the INIT IPIs here are invalid, but other systems follow the MP spec instead. While here, fix the IPI wait routine to accept a timeout in microseconds instead of a raw spin count, and don't spin forever during AP startup. Instead, panic if a STARTUP IPI is not delivered after 20 us. PR: 196542 Differential Revision: https://reviews.freebsd.org/D1719 MFC after: 2 weeks |
